Packet switching testing method and apparatus

U.S. Patent Number: 5383177

Abstract: A packet section (21) generates each packet data by adding a packet header to each of a plurality of random patterns. A highway demultiplexing section (22) demultiplexes the generated packet data to a plurality of input highways. A packet multiplexing section (32) multiplexes the packet data to one highway, the packet data being supplied from the plurality of output highways. A depacket section (31) fetches each random pattern out of the packet data multiplexed by the packet multiplexing section. An error detector (7) detects an error in the random pattern fetched by the depacket section. A test for an under-test device is thus conducted.
